السؤال #1
A BIG-IP has two load balancing virtual servers at 150.150.10.10:80 and 150.150.10.10:443. The port 80 virtual server has SNAT automap configured. There is also a SNAT configured at 150.150.10.11 set for a source address range of 200.200.1.0 / 255.255.255.0. All other settings are at their default states. If a client with the IP address 200.200.1.1 sends a request to https://150.150.10.10, what is the source IP address when the associated packet is sent to the pool member?
A. 200
B. 150
C. Floating self IP address on VLAN where the packet leaves the system
D. Floating self IP address on VLAN where the packet arrives on the system

السؤال #4
Assume a client's traffic is being processed only by a NAT; no SNAT or virtual server processing takes place. Also assume that the NAT definition specifies a NAT address and an origin address while all other settings are left at their defaults. If the origin server were to initiate traffic via the BIG-IP, what changes, if any, would take place when the BIG-IP processes such packets?
A. The BIG-IP would drop the request since the traffic didn’t arrive destined to the NAT address
B. The source address would not change, but the destination address would be changed to the NAT address
C. The source address would be changed to the NAT address and destination address would be left unchanged
D. The source address would not change, but the destination address would be changed to a self-IP of the BIG-IP

The ICMP monitor is failing for 2 of the pool member 5 nodes. All other settings are default. What is the status of the monitor is working in all cases?
A. All pool members are up since the HTTPbased monitor is successful
B. All pool members are down since the ICMPbased monitor is failing in some cases
C. The pool members whose nodes are failing the ICMPbased monitor will be marked disabled
D. The pool members whose nodes are failing the ICMPbased monitor will be marked unavailable

A. The pool member would be marked offline (red)
B. The pool member would be marked online (green)
C. The pool member would be marked unknown (blue)
D. The pool member would alternate between red and green

A site has six members in a pool. All of the servers have been designed, built, and configured with the same applications. It is known that each client's interactions vary significantly and can affect the performance of the servers. If traffic should be sent to all members on a regular basis, which loadbalancing mode is most effective if the goal is to maintain a relatively even load across all servers?
A. Ratio
B. Priority
C. Observed
D. Round Robin
